To all whom, it may concern.:

Be it known that I, JOHN B. GILLIE, a citizen of the United States, residing at Northv Tonawanda, in the county of Niagara and State oi New York, have invented certain new and useful Improvements in Portable Planing-Machines; and I do hereby declare the -following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to portable planing- `machines, and is-particularly designed for planing valve-seats of marine engines, but may be used generally, if desired.

The primary object of my invention is to provide a machine which can be quickly and conveniently applied to a marine engine located in a boat to plane the valve seat or seats thereof.

Other objects are to provide an inexpensive, eifective, and reliable planer which may be operated by hand or power, to provide means for adjusting the frame or guides of the machine relative to the valve-seat to cause the cutting-tool to properly plane the latter, and to provide an extensible reciprocating carriage which can be adjusted to any size engine.

To these ends the inventionconsists of the new and novel construction, arrangement, and combination of parts, as will be hereinafter described, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a iront elevation of my improved portable planer. Fig. 2 is a horizontal section taken on line W W, Fig. 1. Fig. 3 is an enlarged horizontal section taken on line X X, Fig. 1. Fig. 4 is an enlarged horizontal section taken on line Y Y Fig. 1. Fig. 5 is a vertical section taken on line Z Z, Fig. 4.

Referring to the drawings in detail, like numerals of reference refer to like parts in the several igures.

The reference-numeral 1 designates part of an engine showing part of the cylinder 2, the valve-chamber 3, and the engine-frame 4, In the wall 5, located between the valve-chamber and the cylinder, are the inlet and exhaust ports 6, and the outer face 7 of the said wall serves as a valve-seat for a slide-valve, as is common in steam-engines. The valvecasing is provided with an external ange 8,

having stud-bolts 9 secured therein, by means of which and coacting nuts a plate or other suitable closure is aflixed.

In applying my improved planing-machine to the engine the plate or closure just referred to is removed, and by means oisuitable clamping-plates or keepers cooperating with the stud-bolts 9 the machine can be quickly and conveniently applied to the casing of the valve-chamber.

The planing-machine comprises two parallel vertical frame-bars 10, preferably cylindrical in cross-section, which extend from the floor 11 to a point above the upper edge of the valve-chamber. The said frame-bars' are positioned on opposite sides and in advance of the valve-seat and are held between stud-bolts j on the upper and lower horizontal flanges, which stud-bolts serve, with the aid of keepers 12, to clamp the said bars to the valve-chamb er at the four corners thereof. Each keeper consists of two clamping plates, between which. and the stud-bolts above referred to the parallel Jframe-bars 10 are secured. The inner clamping-plate 13 of each keeper is slotted lengthwise, as at 14, and at each end has a set-screw 15 passing therethrough,which set-screws are adapted to bear with their ends against the flanges of the valve-casing, and on turning said set-screws in either direction the said clamping-plate, which serves as an adjustinglate, can be moved toward and from the va ve-chamber. The said adjusting-plates are carried on the stud-bolts, between which the frame-bars 10 are held. The outer clamping-plate 16 of each keeper is also provided with a longitudinal slot 17 to permit the same to be passed over the stud-bolts, and the said clamping-plates 16 are forced against said iframe-bars by means of nuts 18, screwed onto the projecting ends of the said stud-bolts. By adjusting the inner plates 13 of the keepers the frame-bars 10 may be quickly adjusted with reference to the valve-seat, and the said bars may also be adjusted laterally between the clampingplates by loosening the outer plate.

19 designates an extensible reciprocating carriage which comprises two -cylindrical cross-bars 20 and slide-heads 21, arranged for reciprocal movement on the frame-bars.

Each slide-head is provided with a vertical socket 22, which encircles one of the iframebars and by means of which the reciprocating carriage is guided on said frame-bars, and two horizontal sockets 23, in which the cross- IOO 'arms 27. Pitmen28 are secured with their lower terminals to crank-arms 27 and with their upper terminals to `lateral extensions 29 ,formed on the slide-heads 2l. On revolving the crank-shaft 21 the carriage is reciprocated vertically on the frame-bars through the medium of the said pitmen.

I have illustrated one form of power drive;

but any other means for revolving the crankshaft may be resorted to, if desired. I have shown a bevel-gear 30, secured to the crankshaft, which meshes with a bevel-gear 3l secured to a counter-shaft 32 having secured to its other end a spur-gear 34, which meshes with a pinion 35, secured to the main shaft 36, having the belt-pulley 37 affixed thereon. The main shaft 36 and the counter-shaft 32 are journaledinbearings 38, supported in'any suitable manner.

In many instances the space below the cylinder and between the engine-frame is taken up with the mechanism of the engine, and it is necessary to adjust the crank-shaft so as not to interfere with the said mechanism. This I do by forming the bearings 26 in two sections, one section 39 being a securing-section secured to the frame-bars 10and the other section 40 being a bearing-section adjustable on the securing-section. The front end of the securing-section is bifurcated, as at 4l, to receive a rearwardly-extending lug 42, having an aperture 43 formed therein. An adjusting-bolt 44 is passed through slots 45, formed in the bifurcated securing-section.

and through the aperture 43 and serves to hold the two sections together in any adjusted relation. In this -manner the crankshaft can be moved away from the mechanism of the engine.

A46 designates the tool-holder, which is moved laterally intermittently on the crossbars 20 of the reciprocating carriage. A cutting-tool 47 is provided which is adjustably secured to the tool-holder in any suitable manner and is designed to plane the valve-seat on its upward movement. As is common in planers, the tool is inactive on its return stroke, and during such movement the tool-holder is moved laterally to bring the tool in line with the contiguous uncut part of the valve-seat. The intermittent lateral movement or feed of the tool is effected through the medium of the feedscrew 48, which is held from lengthwise movement in one of the slide-heads 21 and has threaded connection with the tool-holder 46. To one end of the said feed-screw a toothed wheel 49 is secured, and as the reciprocating carriage is moved upward said toothed wheel engages the under side of a hinged or pivoted dog 50 and deilects the same, while on the downward movement of the carriage the said toothed wheel engages the upper side of said dog and is caused to revolve until the tooth engaging the dog clears the same. The pawl 50 is hinged to an arm 5l, held adjustable in any suitable manner to the valve-chamber.

Having thus described my invention, what I claim isl. In a portable planer adapted to plane the valve-seat of an engine, the combination with stud-bolts projecting from the enginecasing, of an open frame comprising two vertical frame-bars adapted to be positioned between said stud-bolts, adjustable plates having each a longitudinal slot adapted to fit onto said stud-bolts and being located between said frame-bars and the valve-casing, set-screws passing through the adjustingplate and serving to hold the latter any desired distance from the valve-casing, clampinglates having each a longitudinal slot and eing adapted to fit over said stud-bolts and bear against the frame-bars, and securing-nuts engaging the ends of said stud-bolts and serving to force said clamping-plate against the frame-bars to hold the same securely against the adjusting-plates.
